Description

Liquid crystal screen wave-soldering bearing plate

Technical Field

The utility model belongs to the welding equipment field, concretely relates to LCD screen wave-soldering loading board.

Background

The liquid crystal screen is a common display device, belongs to a flat panel display, and is used for information display of a plurality of electronic devices, including an intelligent closestool. The liquid crystal display has the advantages of low power consumption, small volume and low radiation. The liquid crystal display screen uses liquid crystal solution in two pieces of polarization materials, so that the crystal can be rearranged to achieve the purpose of imaging when current passes through the liquid. Wave soldering needs to be carried out through a wave soldering machine in the production process of the liquid crystal screen, the liquid crystal screen and the PCB need to be fixed in the machining process, and displacement is prevented from occurring in the welding process, so that the liquid crystal screen cannot work. The existing fixing modes are simple and even manually fixed, and the fixing mode is very inefficient.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome exist not enough among the above-mentioned prior art to a LCD screen wave-soldering loading board is provided.

The utility model provides a technical scheme that its technical problem adopted is:

the utility model provides a LCD screen wave-soldering loading board, includes the support plate, its characterized in that: a hollow body is arranged in the support plate, a plurality of support plates which are arranged at equal intervals are arranged in the hollow body, a front support block and a rear support block are respectively arranged at two sides of each support plate, and positioning columns which are vertically fixed on the support plate are arranged beside two ends of each support plate; the two sides of the hollow-out body are provided with a plurality of pressing plates, the pressing plates are fixed on the support plate through screws and can rotate by taking the screws as axes, the bottoms of the pressing plates are inwards sunken to form grooves, and outwards convex glue layers are arranged in the grooves.

Furthermore, the periphery of the support plate is provided with a coaming perpendicular to the upper surface of the support plate, and the height of the coaming is greater than that of the pressing plate.

Compared with the prior art, the utility model, have following advantage and effect: compact structure, the support plate can be fixed LCD screen PCB board in batches, avoids the wearing and tearing to the PCB board that probably appear simultaneously, can improve the efficiency of LCD screen processing, uses manpower sparingly.

The accompanying drawings, which are included to provide a further understanding of the application and are incorporated in and constitute a part of this application, illustrate embodiment(s) of the application and together with the description serve to explain the application and not to limit the application.

Detailed Description

In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below. In the description of the present invention, it should be noted that the terms "front", "back", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, which are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

Examples

As shown in fig. 1-2, the present embodiment includes a carrier plate 1, a hollow 11 is disposed in the carrier plate 1, and a plurality of support plates 12 are disposed in the hollow 11 and arranged at equal intervals. The two sides of the supporting plates 12 are provided with a front supporting block 121 and a rear supporting block 122, the front supporting block 121 and the rear supporting block 122 between every two adjacent supporting plates 12 correspond to a PCB to be welded, that is, the PCB is placed between any two adjacent supporting plates 12, and the front supporting block 121 and the rear supporting block 122 can support the PCB. The two sides of the hollow-out body 11 are also provided with a front supporting block 121 or a rear supporting block 122 corresponding to the supporting plate 12 close to the side. The positioning columns 13 vertically fixed on the support plate 1 are arranged beside the two ends of the support plate 12, and the positioning columns 13 are used for positioning and limiting the placement position of the PCB, so that an operator can conveniently and quickly place the PCB on the support plate 1.

As shown in fig. 1 and fig. 3, a plurality of pressing plates 2 are disposed at two sides of the hollow body 11, and the pressing plates 2 are fixed on the carrier plate 1 by screws 21 and can rotate around the screws 21. The front end of the pressing plate 2 is provided with a pushing block 22, so that an operator can push the pressing plate 2 to rotate relative to the screw 21 through the pushing block 22, the front end of the pressing plate presses the PCB placed in the hollowed-out body 11, and the displacement of the PCB is prevented. The bottom of the pressing plate 2 is inwards sunken to form a groove, an outwards convex glue layer 23 is arranged in the groove, and the glue layer 23 has certain elasticity, so that elements on the PCB cannot be damaged when the pressing plate 2 moves.

In this embodiment, the surrounding plate 3 perpendicular to the upper surface of the carrier plate 1 is further arranged on the circumferential side of the carrier plate 1, the height of the surrounding plate 3 is greater than that of the pressing plate 2, and when the carrier plate 1 with the PCB placed thereon is turned over and placed, the surrounding plate 3 with a certain height can enable the pressing plate 2 to be relatively free, so that the pressing plate 2 is prevented from falling off due to the fact that the pressing plate 2 is displaced due to collision in the moving process.

The manual welding assistor for the liquid crystal screen described in the embodiment has a compact structure, the carrier plate 1 can fix the liquid crystal screen PCBs in batches, meanwhile, the abrasion to the PCBs which possibly occurs is avoided, the liquid crystal screen processing efficiency can be improved, and the labor is saved.

The above description in this specification is merely illustrative of the present invention. Various modifications, additions and substitutions may be made by those skilled in the art without departing from the scope of the invention as defined in the accompanying claims.
